“It’s really unfortunate because the kid had been playing well,” Bucks coach Larry Drew said of Sanders. “He was starting to play with a rhythm and had played two of his better games this year.”

A Bucks spokesman gave no timetable on Sanders’ return and indicated he would see a specialist on Tuesday. Drew said Sanders still was suffering from blurred vision.

“He was starting to get that energy back and that fire and that passion,” Drew said. “But it’s just really unfortunate.”

Sanders missed six weeks early in the season after undergoing surgery on his right thumb following a bar fight. He returned Dec. 27 at Brooklyn and has played in 20 games since then.

Sanders has averaged 14.3 points (19-of-30 shooting) and 11.3 rebounds in three February games before suffering the injury. For the season he has averaged 7.7 points and 7.2 rebounds while playing 25.4 minutes per game.
